Problems solved by technology

Because this structure is relatively simple, it can only be applied to low-frequency electromagnetic shielding, and often cannot pass the electromagnetic compatibility test
In actual use, it is easy to cause electromagnetic interference with other electromagnetic equipment
Therefore, the traditional shielding structure can no longer meet the shielding requirements in complex electromagnetic environments

Abstract

The invention provides an electromagnetic compatibility shield compartment comprising an outer shielding shell and an inner shell arranged in the outer shielding shell. The outer shielding shell sequentially comprises a glass fiber layer, a plastic layer with both sides plated with metal and a shield layer made of an electromagnetic-wave absorbing material from inside to outside, the inner shell is made of aluminium alloy plates, separated from the outer shield shell and fixedly connected with the outer shield shell through a support, the space between the inner shell and the outer shield shell is filled with conductive foam, a shield door which can be opened and closed is arranged on each of the inner shell and the outer shield shell, the shield door on the inner shell corresponds to the shield door on the outer shield shell in position, the shield door on the inner shell is made of an aluminium alloy plate and is provided with a ventilation opening of a honeycomb structure, and the shield door on the outer shield shell is identical to the outer shield shell in structure. By the means, the electromagnetic compatibility shield compartment has a good electromagnetic compatibility shield function and is applicable to shielding of various electromagnetic waves.

Description

technical field [0001] The invention relates to the technical field of electromagnetic compatibility shielding, in particular to an electromagnetic compatibility shielding cabin. Background technique [0002] Traditional EMC shielding devices usually only use one layer of metal plate to make the shielding cavity. Because this structure is relatively simple, it can only be applied to low-frequency electromagnetic shielding, and often fails to pass the electromagnetic compatibility test. In actual use, it is easy to cause electromagnetic interference with other electromagnetic equipment. Therefore, the traditional shielding structure can no longer meet the shielding requirements in complex electromagnetic environments. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide an electromagnetic compatibility shielding cabin, which can have a good electromagnetic compatibility shielding function and is suitable for shieldi...
